Add to Wishlist
Part# 12-02248
MFR Model# AA473



The Tempest Easy Drain Oil Filter Drain Tool eliminates the most time-consuming aspect of an oil change - the clean up. Easy Drain reduces filter spills, saving time and eliminating the seemingly inevitable mess of changing oil.

Works with 3-1/2" diameter oil filters.

It's as Easy as 1...2...3!
  1. Slip Easy Drain around filter and secure by turning the butterfly knob until tight against the filter. Be sure that the Easy Drain is located at the lowest part of the oil filter can to allow maximum drainage.
  2. Attach hose to the bottom of the T-handle and then twist the T-handle to puncture the filter. Back the T-handle out to original position to allow the oil to drain.
  3. Drain oil into pan. Go grab a friend and have lunch because this process will take awhile! The oil drains slowly no matter what temperature it is because the media pack is saturated with oil. Be patient!

I bought this tool to help with oil changes on my truck. It required a slight modification due to the filter diameter, but it works perfectly. Nice product!

Works like a dream, 1/2 silicone hose allows for quick draining. Purchased a few various wire clamps for dust exhaust systems and have fit this to several sideways filters already outside of airplanes

This is an excellent tool. For the first time, I was able to remove the oil filter on my Lycoming IO-360 in my Cessna 172R without spilling a drop of oil on the hangar floor during my oil change. I left the unit in place to drain the oil overnight and that worked perfectly. I did have to buy a longer plastic drain hose from the hardware store because the hose supplied with the device wasnt quite long enough for me. Ive tried other strategies for a clean oil change but this one was by far the best.

Good tool but tax and mail charges made it very expensive for a clamp and screw tool.

This simple device turns a messy task into a clean one

Bought it to use on cars, since it has a wire clamp I simply change it out for a smaller sized one for smaller filters. Now the people that say the hose is worthless, well its vinyl so just heat it up with a hair dryer or a heat gun and VOILA! straight without any kinks. I like this as I can use it on a hot car, boat or plane and just let it drain, at times overnight. I have an oil drain valve that pretty much does the same thing, where a hose directs the oil to a canister. This has made my oil changes much easier and since Im not trying to rush whatever Im working on out the door to start the next one I like the cleanliness of it. If you have the room around the oil filter and hate having to clean up after you make a mess this is well worth it. Price could be lower though, I mean it is a hose clamp and a plastic valve, but I guess as the demand isnt that high for it...

Great tool if have enough space. Unfortunately does not work on my Beechcraft Sundowner 1976 with very tight space and the engine frame on the way. There is so much around the oil filter that it is difficult to mount it on and impossible to connect the hose or turning the knob to create the hole.

The device worked well. The hose that came with it was so short it didnt reach beloe the cowl of my Mooney 201.

The screw clamp that came with it does not fit around the filters for the Volvo D13s. After having to modify it with new clamps. It works. Other than modification, the screw mechanism works great.

Q: Will the Tempest AA473 Oil Drain Tool work on a Champion filter?

Yes, this will work on Tempest, Champion, and other 3-1/2" diameter filters.

Per Vendor: Yes, it will work on different filters and positions. So it can work in the horizontal and vertical position.

Q: What is the max diameter filter it will fit around?

Approx max dia. 4 inches.

Q: Will the Tempest AA473 work on an RV10? Any purchasers of RV10s comment?

We do not have an aircraft application. It will work with all Tempest, Champion, and 3-1/2 inch diameter filters.
